Answers
Answer:
1) False
2) True
3) a) True b) False
4) False
Step-by-step explanation:
1)
Two-point are collinear if they lie in the same line. The vector -2AB is antiparallel to the vector AB then it is False.
2)
A unit vector could be difinede as:
[tex]\vec{u}=\frac{\vec{v}}{|\vec{v}|}[/tex]
Terefore, [tex]\frac{1}{AB}\vec{AB}[/tex] is a unit vector. It is True.
3)
a) If AB=-3AC
The points, A, B, and C are collinear, because all of them lie in the same line. True
b) Let's take the modulus in each side.
[tex]\vec{AB}=-3\vec{AC}[/tex]
[tex]|\vec{AB}|=|-3\vec{AC}|[/tex]
[tex]|\vec{AB}|=|-3||\vec{AC}|[/tex]
[tex]|\vec{AB}|=3|\vec{AC}|[/tex]
So it is False.
4)
If we put the vector AI = 3/2 AB into the first equation we will have:
[tex]2(-\frac{3}{2}\vec{AB})+3\vec{IB}=-3\vec{AB}+3\vec{IB}[/tex]
And we can not say that it is a cero vector, so it is False.
I hope it helps you!

D. 9 degrees (go to card 3)
Answers
Answer:
Step-by-step explanation:
The value of the measure of the smaller angle is,
⇒ 11 degree
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
Two angles are complementary.
And, The larger angle is 46 degrees more than three times the smaller angle.
Now, Let the smaller angle = x
Hence, Value of larger angle = 46 + 3x
Since, Both angles are complementary.
Hence, We get;
x + (46 + 3x) = 90
4x + 46 = 90
4x = 90 - 46
4x = 44
x = 11
Thus, The value of the measure of the smaller angle is,
⇒ 11 degree

Answer:
You can get 25 packs of 20 and 3 packs of 9 and 1 4 piece.
OR

Answer:
24 packs of 20=480
3 packs of 9=27
2 packs of 6=12
3 packs of 4=12
480+27+12+12=531

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
Enter your answer in the box
Answers
Answer:
m∠A = 116°
Step-by-step explanation:
For better understanding of the solution, see the attached figure of the problem :
The quadrilateral ABCD is inscribed in a circle, Thus the quadrilateral ABCD is a cyclic quadrilateral.
Also, Sum of opposite angles of a cyclic quadrilateral is supplementary.
Now, m∠A = (x - 36)°, m∠B = 28° and m∠D = x°
But, since the sum of opposite angles is 180°
⇒ 28° + x° = 180°
⇒ x = 180 - 28
⇒ x = 152
So, m∠A = (x - 36)°
⇒ m∠A = (152 - 36)°
⇒ m∠A = 116°

Answer:
Total gallon of fuel used = [tex]11.428[/tex] gallons

Given -
The total distance travelled by car in one gallon of gas = 21 miles
Total distance travelled each day = 48 miles
Number of days days in a week in which Candice drive is 5 days
Total miles travelled per week = [tex]48*5[/tex] = 240 miles
Total gallon of fuel used = [tex]\frac{240}{21} = 11.428[/tex] gallons

find constants p and q such that x^4-2x^3-x^2+2x+10=(x^2+px+5)(x^2+qx+2)
Answers
Answer:
p = -4 q = 2
Step-by-step explanation:
Expand the brackets ( yes the entire thing).group together the values with same co-effiecients; like (q+p)x^3 etc etc.equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].sub in this value for the [x^3] equation and ull get an answer for p [p= -4].hope my explanation is understandable lol
In January Todd was able to lift 127 1/2 lb. In February he could lift 135 lb, and in March he could lift 142 1/2 lb. If he continues at this rate what will Todd be able to lift in July?
Answers
Answer:
172 1/2 lb
Step-by-step explanation:
Determine the rate of change per month = lifts lifted in march - lift lifted in February
142 1/2 - 135 = 7 1/2
Determine the number of months from march to July = 4
increase in weight he would be able to carry in 4 months = 7.5 x 4 = 30 lb
weight he would be able to carry in april = 30 + 142 1/2 = 172 1/2
